Nanowire-based THz polarimetry

Semiconductor nanowires show extreme polarization selectivity for both visible and terahertz photons. We are utilising an in-depth knowledge of ultrafast charge-carrier dynamics in nanowires to develop unique devices for THz polarimetry. Our photoconductive THz sensors based on a hash-nanowire architecture are compact and recover the full polarisation state of THz pulses. These nanowire-based devices are showing promise in areas including semiconductor characterisation and the development of metamaterials for THz polarisation manipulation.
